The Relay Connections
85: Connects to the start module's trunk release wire output. This becomes the negative trigger for the coil.
86: Connects to a fused +12 volt source.
87: Connects to a negative source (where the remote start module is grounded). This becomes the supply for
activating the vehicle's trunk release wire.
87A: No connection. This terminal is not used in this application.
30: Connects to the vehicle's trunk release wire.
Comments: At rest the relay is not active and the vehicle's trunk release switch is allowed to operate normally.
When the trunk release button is pressed, the start module's trunk release output activates the relay. The
ground signal is sent from 87 through 30 to the vehicle's trunk release wire activating the switch and opening
the trunk.
Clutch
Bypass
In order to remote start a manual transmission vehicle, the clutch switch must be bypassed. Clutch safety
switch circuits can take many forms. Listed below are the most common ones. When testing to determine the
type of clutch circuit, it is recommended to use a computer safe logic probe. Some vehicles may also have a
separate or combined switch on the clutch pedal for cruise control. Usually a cruise control switch reacts the
moment you touch the pedal, where as a clutch switch reacts only when the pedal is near the floor. Once the
circuit type has been determined, you must recreate what happens electrically at the switch, with the remote
start module, to bypass the clutch during remote starts. Relays are often used to accomplish this. Always use
the Ground Out When Running (G.O.) as the negative trigger on your clutch bypass relays, as it is only active
during remote starts. NEVER permanently bypass a clutch switch. Do not attempt this if you are unfamiliar
with the use of relays, and diode isolation.
Before any Hot Wiring attempts:
Test and record the way each wire tests in the following positions:
With out the pedal pressed:
•
Test the wires with the Ignition OFF
•
Test the wires with the Ignition ON
•
Test the wires with the Key in the start position
With the pedal pressed:
•
Test the wires with the Ignition OFF
•
Test the wires with the Ignition ON
•
Test the wires with the Key in the start position
With this information for every wire at the switch, determining what type of clutch switching system you have will
be easy.
Direct Feed:
The simplest type of system to test and bypass is the “Direct Feed” system. This circuit simply interrupts the
+12v signal starter wire from the ignition switch to the starter solenoid. There are 2 wires in this circuit, the “key
side” wire which goes from the clutch pedal to the Ignition switch, and the “solenoid side” which goes from the
clutch switch to the starter motor. When the key is turned to the start position without pressing the pedal, you
will test 12v only on one of the wires at the clutch switch, this is the key side. When the pedal is pressed down,
and the key is in the crank position, the other wire will also read 12 volts; this is the solenoid side wire. To
confirm you have a direct feed clutch switch, hot wire the “solenoid side” wire with a fused +12 volts and the
starter motor will crank. Connect the starter output from the remote starter to solenoid side wire.
Note: In the next two systems a Relay in the vehicle interrupts the start wire between the Ignition switch and
the starter motor. With the key in the start position, and the clutch pedal pressed, the relay energizes and
allows the start signal to reach the starter motor. In these systems a wires from the clutch triggers the relay,
when the pedal is pressed. There will be another wire at the clutch switch that supplies the signal to the trigger
wire (either positive or negative, depending on the system)
Negative:
In a Negative system, when the clutch is pressed; a negative signal is sent to the relay, the relay energizes,
when the Key is turned to the start position the 12volts from the start wire is allowed to pass through the relay
and to starter motor. One of the wires at the clutch will test as negative, this is the supply wire. The relay's
negative trigger wire will only show negative when the pedal is pressed (some vehicle's also require the Ignition
